PIANO-PEDAL.

Specification of Letters Patent.

Patented Oct. 1, 1907.

Application filed January 10, 1907. Serial No. 351,681.

To all whom it may concern:

Be it known that I, EARL P. SEDG WICK, a citizen of the United States ofAmerica, and a resident of Highland Park, in the county of Lake andState of Illinois, have invented certain new and useful Improvements inPiano-Pedals, of which the following is a specification.

This invention relates to the pivotal connections between piano pedalsand their supporting brackets or standards, and has for its object toprovide a simple and efficient structural formation and combination ofparts affording a ready removal and replacement of the pedals, aneffective adjustment to take up wear and avoid lost motion, and which atthe same time provides a very durable and economical construction, allas will hereinafter more fully appear.

In the accompanying drawings:-Figure l, is a plan view illustrating thepresent improvement applied to a piano pedal of the end pivot type. Fig.2, is a similar view illustrating the application of the same to a pianopedal of the intermediate pivot type. Fig. 3, is an enlarged detailsection on line Fig. 1. Fig. 4, is a detail plan view of the supportingbracket or standard.

Similar numerals of reference indicate like parts in the several views.

Referring to the drawings, 1 represents the flat attaching base memberof the supporting bracket or standard, and which is preferably formedwith ends 2 curved laterally in opposite directions and formed withorifices for the passage of the screws by which attachment is made tothe bottom board of a piano. As so constructed said orifices lay to thesides of the pedal, when the same is in place, and no interference willbe met in a ready and convenient application or removal of the attachingscrews aforesaid.

3, are a pair of upright side members on the base 1, and formedintegrally therewith, preferably as a sheet metal stamping bent into theform of bracket or standard shown in the drawing. Such side members havea separated relation equal to the width of the shank portion of thepiano pedal so that the pedal shank may be located there between; andeach member will be formed near its top with a horizontal pit ordepression 4, in alined and opposed relation to the pit or depres sionof the companion side member, such pits or depressions forming journalbearings for the piano pedal as hereinafter described.

5, is the piano pedal of any usual form and having a flat rectangularshank by which it is pivotally attached within the body of the piano. Inthe present improvement such pedal shank is provided with outwardlyprojecting studs 6 integrally formed on the sides of said shank, andadapted to have journal bearing in the aforesaid pits or depressions 4of the supporting bracket or standard.

The studs 6 and depressions 4, are preferably of the rounded form shown,but any other suitable form may be imparted thereto without departingfrom the spirit of this part of the present improvement.

7, is a headed bolt extending transversely through the upright sidemembers 2 of the supporting bracket, midway the height of the same, andprovided at one end with a nut 8, by the adjustment of which the uprightside members are sprung towards each other to effect the connection ofthe journal depressions 4 and studs 6 in a ready and substantial manner,as well as to permit a ready detachment of the parts by a reversemovement of said nut.

Having thus fully described my said invention what I claim as new anddesire to secure by Letters Patent is:-

17 The combination in a piano pedal, of a supporting bracket formed witha fiat attaching base and a pair of upright side members having neartheir upper ends p posed journal depressions, a pedal the shank of whichis provided with journal studs on its sides for engagement in saiddepressions, and a transverse bolt arranged midway the height of theside members and adapted to draw the same together; substantially as setforthv 2. The combination in a piano pedal, of": a supporting bracketformed with a flat attaching base having attach ing ends curvedlaterally in opposite directions and with a pair of upright side membershaving near their upper ends opposed journal depressions, a pedal theshank of which is provided with journal studs on its sides forengagement in said depressions, and a transverse bolt arranged midwaythe height of said members and adapted to draw the same together,substantially as set forth.

Signed at Highland Park Ills. this th day of January 1907.
